Ultra-High Performance NFCA Modules. L30 adopts the same NFCA(nested feedback composite amplifier) module from flagship A90. Voltage Current hybrid feedback architecture along with UHGF (Ultra High Gain Feedback) technology provides excelletn DC and AC performance.
Wide Applications for Headphones. L30 has a high voltage swing of 26Vp-p, power of 3500mW per channel when both channels are driven and output impedance of less than 0.1ohm. It easily drives power for headphones with a wide range of different impedance.
3 Steps Gain Settings. L30 is equipped with three gain settings of -9.9dB/0dB/9.5dB.Wide range of gain settings and the 0.3uVrms ultra-low noise makes L30 easily adapt to all types of headphones from extremely sensitive IEMs to most power demanding full-sized over-ears
High Quality Amplifier. The NFCA modules of L30 are not only able to drive the headphones but also apply to be a pre-amplifier with the same ultra-high performance. When it is in preamp mode, the output impedance is as low as 20 ohm, which is widely suitable for various devices. It is a great companion of active monitors stacked with E30 DAC when L30 working in preamp mode
Perfect Companion for Audiophile. Designed with a portable and compact body, L30 could be your HiFi device on-the-go for every day life. Simply take it anytime anywhere, you will enjoy pure high fidelity music
